ABSTRACT

Disclosed are a UCI combined transmission method, a terminal, and a network device. The method comprises: when determining that a transmission resource of a first UCI overlaps transmission resources of a plurality of second UCIs in a time domain, a terminal selects the transmission resource of one second UCI from the transmission resources of the plurality of second UCIs according to an initial position of the transmission resource of the first UCI and the initial position of the transmission resources of the second UCIs, so as to simultaneously transmit the first UCI and the selected second UCI on the transmission resource of the selected second UCI. Accordingly, a network can also simultaneously receive the first UCI and the selected second UCI on the transmission resource of the selected second UCI with the same method. By means of the method, it can be ensured that the understandings of the base station and the terminal on the UCI combined transmission are consistent in the case that transmission resources of different UCIs overlap in the time domain.

FIELD

The application relates to the field of terminal technology, and inparticular to a UCI combined transmission method, a user equipment and anetwork-side device.

BACKGROUND

With the development change of the mobile communication service demand,the International Telecommunication Union (ITU), the 3rd GenerationPartnership Project (3GPP) and other organizations all begin to researchnew wireless communication systems, e.g., 5 Generation New Radio AccessTechnology (5G NR).

In the current 5G NR system, the Uplink Control Information (UCI) can betransmitted using the NR Physical Uplink Control Channel (PUCCH). The NRPUCCH formats include 5 types of PUCCH formats: format 0, format 1,format 2, format 3 and format 4, wherein the PUCCH format 0 or 1 maycarry 1 bit to 2 bits UCI, and the PUCCH format 2, 3 or 4 may carry theUCI greater than 2 bits; the PUCCH format 0 or 2 are the short PUCCH andmay occupy 1 symbol to 2 symbols for transmission, and the PUCCH format1, 3 or 4 are the long PUCCH and may occupy 4 to 14 symbols fortransmission.

The UCI may be a Hybrid Automatic Repeat reQuest-Acknowledgement(HARQ-ACK), which can be transmitted using the NR PUCCH format 0 or 1 or2 or 3 or 4; or the UCI may be a Scheduling Request (SR), which can betransmitted using the NR PUCCH format 0 or 1; or the UCI may be theperiodic Channel State Information (CSI), which can be transmitted usingthe NR PUCCH format 2 or 3 or 4.

In the 5G NR system, the PUCCH formats used by transmission resources ofdifferent UCIs are independently configured, so the transmissionresources of different UCIs may overlap in the time domain, but a userequipment can only transmit one PUCCH at an uplink moment on a carrier.There is a need to solve the problem of how to transmit UCIs.

SUMMARY

The embodiments of the application provide a UCI combined transmissionmethod, a user equipment and a network-side device, so as to solve theproblem of how to transmit UCIs when the transmission resources ofdifferent UCIs overlap in the time domain.

DETAILED DESCRIPTION

The application will be illustrated below in combination with thedrawings of the specification, and the operation methods according tothe method embodiments may also be applied in the device embodiments.

As shown in FIG. 1, an embodiment of the application provides a systemfor transmitting the UCI, which includes: a user equipment 101 and anetwork-side device 102.

The user equipment 101 is configured to: when determining that atransmission resource of a first UCI and transmission resources of aplurality of second UCIs overlap in a time domain and transmissionresources of any two of the plurality of second UCIs do not overlap inthe time domain, select a transmission resource of a second UCI amongthe transmission resources of the plurality of second UCIs, and transmitthe first UCI and the second UCI carried by the selected transmissionresource of the second UCI simultaneously on the selected transmissionresource of the second UCI. The user equipment can be a variety of typesof user equipments, such as notebook computer, smart phone, tabletcomputer, smart TV, and so on.

The network-side device 102 is configured to: when determining that thetransmission resource of the first UCI and the transmission resources ofa plurality of second UCIs overlap in the time domain and thetransmission resources of any two of the plurality of second UCIs do notoverlap in the time domain, select a transmission resource of a secondUCI among the transmission resources of the plurality of second UCIs,and receive the first UCI and the second UCI carried by the selectedtransmission resource of the second UCI simultaneously on the selectedtransmission resource of the second UCI.

In this way, when the transmission resources of a plurality of secondUCIs and the transmission resource of the first UCI overlap in the timedomain, the user equipment can select a transmission resource of asecond UCI among the transmission resources of the plurality of secondUCIs according to the start position of the transmission resource of thefirst UCI and the start positions of the transmission resources of thesecond UCIs, and then transmit the first UCI and the second UCI carriedby the selected transmission resource of the second UCI simultaneouslyon the selected transmission resource of the second UCI.Correspondingly, the network side can also use the same method toreceive the first UCI and the second UCI carried by the selectedtransmission resource of the second UCI simultaneously on the selectedtransmission resource of the second UCI. The above method can ensurethat the base station and the user equipment have the same understandingof UCI combined transmission when the transmission resources ofdifferent UCIs overlap in the time domain; and the above method can alsoavoid the redundant transmission of the first UCI while ensuring thatthe base station can obtain the UCI timely.

As shown in FIG. 2, it is a flow schematic diagram corresponding to aUCI combined transmission method according to an embodiment of theapplication. This method can be performed by a user equipment andincludes the following steps.

Step 201: the user equipment determines that a transmission resource ofa first UCI and transmission resources of a plurality of second UCIsoverlap in the time domain, and transmission resources of any two of theplurality of second UCIs do not overlap in the time domain.

In the embodiment of the application, the transmission resource may bePUCCH resource, that is, the transmission resource of the first UCI maybe PUCCH resource used by the first UCI, and the transmission resourceof the second UCI may be PUCCH resource used by the second UCI.

Since the transmission resource of the first UCI and the transmissionresources of the plurality of second UCIs are independently configured,the transmission resource of the first UCI and the transmissionresources of the plurality of second UCIs may overlap in the timedomain. For example, for the first UCI, when the number of symbolsoccupied by the transmission resource of the first UCI is large, aplurality of second UCIs may be transmitted within the time domain rangeof the first UCI transmission. This case is that the transmissionresource of the first UCI and the transmission resources of a pluralityof second UCIs overlap in the time domain. For the plurality of secondUCIs, the transmission resources of any two of the plurality of secondUCIs need to meet the condition of non-overlapping in the time domain.

There are many cases where the transmission resource of the first UCIand the transmission resources of a plurality of second UCIs overlap inthe time domain. One case is that the transmission resource of the firstUCI and the transmission resources of a plurality of second UCIs overlapcompletely in the time domain. As shown in FIG. 3a , it is one ofschematic diagrams where the transmission resource of the first UCI andthe transmission resources of a plurality of second UCIs overlap in thetime domain according to an embodiment of the application. Thetransmission resource of the first UCI is PUCCH-0, which occupies 8symbols; the transmission resource of one of two second UCIs is PUCCH-1,which occupies 2 symbols, and the transmission resource of the othersecond UCI is PUCCH-1, which occupies 2 symbols. It can be seen fromFIG. 3a that the transmission resource (PUCCH-0) of the first UCIoverlaps completely with the transmission resources (PUCCH-1, PUCCH-2)of the two second UCIs.

Another case is that the transmission resource of the first UCI and thetransmission resources of a plurality of second UCIs overlap partiallyin the time domain. As shown in FIG. 3b , it is a second one ofschematic diagrams where the transmission resource of the first UCI andthe transmission resources of a plurality of second UCIs overlap in thetime domain according to an embodiment of the application. Thetransmission resource of the first UCI is PUCCH-0, which occupies 8symbols; the transmission resource of one of two second UCIs is PUCCH-1,which occupies 2 symbols, and the transmission resource of the othersecond UCI is PUCCH-1, which occupies 2 symbols. It can be seen fromFIG. 3b that the transmission resource (PUCCH-0) of the first UCIoverlaps partially with the transmission resources (PUCCH-1, PUCCH-2) ofthe two second UCIs.

Another case is that the transmission resource of the first UCI overlapcompletely with the transmission resources of some second UCIs in thetime domain, and overlap partially with the transmission resources ofsome second UCIs in the time domain. As shown in FIG. 3c , it is a thirdone of schematic diagrams where the transmission resource of the firstUCI and the transmission resources of a plurality of second UCIs overlapin the time domain according to an embodiment of the application. Thetransmission resource of the first UCI is PUCCH-0, which occupies 8symbols; the transmission resource of one of two second UCIs is PUCCH-1,which occupies 2 symbols, and the transmission resource of the othersecond UCI is PUCCH-1, which occupies 2 symbols. It can be seen fromFIG. 3c that the transmission resource (PUCCH-0) of the first UCIoverlaps partially with the transmission resource (PUCCH-1) of a secondUCI, and overlaps completely with the transmission resource (PUCCH-2) ofthe other second UCI.

Step 202: the user equipment selects a transmission resource of a secondUCI among the transmission resources of the plurality of second UCIsaccording to a start position of the transmission resource of the firstUCI and start positions of the transmission resources of the secondUCIs.

In an embodiment of the application, the methods of selectingtransmission resource of a second UCI according to the relationshipbetween the start position of the transmission resource of the first UCIand the start positions of the transmission resources of the second UCIsmay include the following two methods.

First method: when the user equipment determines that the start positionof the transmission resource of the first UCI is not later than thestart position of a transmission resource of any second UCI or a firstsecond UCI or a second UCI with the earliest start position among thetransmission resources of the plurality of second UCIs, then the userequipment determines the transmission resource of the first second UCIor the second UCI with the earliest start position among thetransmission resources of the plurality of second UCIs as the selectedtransmission resource of the second UCI.

Specifically, as shown in FIG. 4a , it is one of examples where thestart position of the transmission resource of the first UCI is notlater than the start positions of the transmission resources of thesecond UCIs according to an embodiment of the application. The startposition of the transmission resource of the first UCI is the position Ashown in FIG. 4a , the start position of the transmission resource ofthe second UCI-1 is the position B shown in FIG. 4a , and the startingposition of the transmission resource of the second UCI-2 is theposition C shown in FIG. 4a . It can be seen from FIG. 4a that the startposition (position A) of the transmission resource of the first UCI isaligned with the start position (position B) of the transmissionresource of the second UCI-1, the start position (position A) of thetransmission resource of the first UCI is earlier than the startposition (position C) of the transmission resource of the second UCI-2,and the start position (position B) of the transmission resource of thesecond UCI-1 is earlier than the starting position (position C) of thetransmission resource of the second UCI-2. That is, the start positionof the transmission resource of the first UCI is no later than the startposition of the transmission resource of any one of the second UCI-1 andthe second UCI-2, or it can also be regarded as: the starting positionof the transmission resource of the first UCI is no later than the startposition of the transmission resource of the first second UCI (i.e.,second UCI-1), or it can also be regarded as: the start position of thetransmission resource of the first UCI no later than the start positionof the transmission resource of the second UCI with the earliest startposition (i.e., second UCI-1). In this way, the user equipment candetermine the transmission resource of the first second UCI among thetransmission resources of these two second UCIs (or the transmissionresource of the second UCI with the earliest start position among thetransmission resources of these two second UCIs), i.e., the transmissionresource of the second UCI-1, as the selected transmission resource ofthe second UCI.

As shown in FIG. 4b , it is a second one of examples where the startposition of the transmission resource of the first UCI is not later thanthe start positions of the transmission resources of the second UCIsaccording to an embodiment of the application. The start position of thetransmission resource of the first UCI is the position A′ shown in FIG.4b , the start position of the transmission resource of the second UCI-1is the position B′ shown in FIG. 4b , and the starting position of thetransmission resource of the second UCI-2 is the position C′ shown inFIG. 4b . It can be seen from FIG. 4b that the start position (positionA′) of the transmission resource of the first UCI is earlier than thestart position (position B′) of the transmission resource of the secondUCI-1, the start position (position A′) of the transmission resource ofthe first UCI is earlier than the start position (position C′) of thetransmission resource of the second UCI-2, and the start position(position B′) of the transmission resource of the second UCI-1 isearlier than the starting position (position C′) of the transmissionresource of the second UCI-2. That is, the start position of thetransmission resource of the first UCI is no later than the startposition of the transmission resource of any one of the second UCI-1 andthe second UCI-2, or it can also be regarded as: the starting positionof the transmission resource of the first UCI is no later than the startposition of the transmission resource of the first second UCI (i.e.,second UCI-1), or it can also be regarded as: the start position of thetransmission resource of the first UCI no later than the start positionof the transmission resource of the second UCI with the earliest startposition (i.e., second UCI-1). In this way, the user equipment candetermine the transmission resource of the first second UCI among thetransmission resources of these two second UCIs (or the transmissionresource of the second UCI with the earliest start position among thetransmission resources of these two second UCIs), i.e., the transmissionresource of the second UCI-1, as the selected transmission resource ofthe second UCI.

Second method: when the user equipment determines that the startposition of the transmission resource of the first UCI is later than thestart position of transmission resource of a first second UCI or asecond UCI with the earliest start position among the transmissionresources of the plurality of second UCIs, then the user equipmentdetermines transmission resource of a second or last second UCI or asecond UCI with the second earliest start position among thetransmission resources of the plurality of second UCIs as the selectedtransmission resource of the second UCI.

Specifically, as shown in FIG. 4c , it is an example where the startposition of the transmission resource of the first UCI is later than thestart position of the transmission resources of the second UCIsaccording to an embodiment of the application. The start position of thetransmission resource of the first UCI is the position A″ shown in FIG.4c , the start position of the transmission resource of the second UCI-1is the position B″ shown in FIG. 4c , and the starting position of thetransmission resource of the second UCI-2 is the position C″ shown inFIG. 4c . It can be seen from FIG. 4c that the start position (positionA″) of the transmission resource of the first UCI is later than thestart position (position B″) of the transmission resource of the secondUCI-1, the start position (position A″) of the transmission resource ofthe first UCI is earlier than the start position (position C″) of thetransmission resource of the second UCI-2, and the start position(position B″) of the transmission resource of the second UCI-1 isearlier than the starting position (position C″) of the transmissionresource of the second UCI-2. That is, the start position of thetransmission resource of the first UCI is later than the start positionof the transmission resource of the first second UCI (i.e., secondUCI-1), or it can also be regarded as: the start position of thetransmission resource of the first UCI is later than the start positionof the transmission resource of the second UCI with the earliest startposition (i.e., second UCI-1). In this way, the user equipment candetermine the transmission resource of the second UCI among thetransmission resources of these two second UCIs (or the transmissionresource of the last UCI among the transmission resources of these twosecond UCIs, or the transmission resource of the second UCI with thesecond earliest start position among the transmission resources of thesetwo second UCIs), i.e., the transmission resource of the second UCI-2,as the selected transmission resource of the second UCI.

In an embodiment of the application, the first UCI and the plurality ofsecond UCIs are any one of: Hybrid Automatic RepeatreQuest-Acknowledgement (HARQ-ACK), periodic Channel State Information(CSI) and Scheduling Request (SR).

Further, the plurality of second UCIs may include second UCIs of thesame message type, for example, the plurality of second UCIs are allHARQ-ACKs, or the plurality of second UCIs are all CSIs, or theplurality of second UCIs are all SRs; or the plurality of second UCIsmay include second UCIs of at least two different message types, forexample, at least one of the plurality of second UCIs is HARQ-ACK, andat least one is CSI; or at least one of the plurality of second UCIs isHARQ-ACK, and at least one is SR; or at least one of the plurality ofsecond UCIs is CSI, and at least one is SR; or at least one of theplurality of second UCIs is HARQ-ACK, at least one is CSI, and at leastone is SR, which are not specifically limited.

It should be noted that, before performing the step 202, the userequipment may further determine whether simultaneous transmission of thefirst UCI and the second UCIs is supported; and the user equipmentselects a transmission resource of a second UCI among the transmissionresources of the plurality of second UCIs according to the startposition of the transmission resource of the first UCI and the startpositions of the transmission resources of the second UCIs when thesimultaneous transmission of the first UCI and the second UCIs issupported.

Step 203: the user equipment transmits the first UCI and the second UCIcarried by the selected transmission resource of the second UCIsimultaneously on the selected transmission resource of the second UCI.

In the embodiment of the application, according to different messagetypes of the first UCI and the second UCI, the user equipment may usedifferent modes for transmission on the selected transmission resourceof the second UCI. The transmission modes can also refer to the methodprovided in the prior art, and will not be described in detail here.

Since the network-side device needs to receive the first UCI and/or thesecond UCI on the PUCCH resources, the network-side device also needs toselect transmission resource of a second UCI among the transmissionresources of the plurality of second UCIs and receive the second UCI andthe first UCI on the selected transmission resource of the second UCIaccording to the user equipment-side method.

As shown in FIG. 5, it is a flow schematic diagram corresponding toanother UCI combined transmission method according to an embodiment ofthe application. This method can be performed by a network-side device(such as base station), and includes the following steps.

Step 501: the base station determines that a transmission resource ofthe first UCI and transmission resources of a plurality of second UCIsoverlap in the time domain, and transmission resources of any two of theplurality of second UCIs do not overlap in the time domain.

The transmission resource may be PUCCH resource, that is, thetransmission resource of the first UCI may be PUCCH resource used by thefirst UCI, and the transmission resource of the second UCI may be PUCCHresource used by the second UCI.

It should be noted that the method for the base station to determinewhether the transmission resource of the first UCI and the transmissionresources of the plurality of second UCIs overlap in the time domain mayrefer to the content described on the user equipment side above, andwill not be described in detail here.

Step 502: the base station selects a transmission resource of a secondUCI among the transmission resources of the plurality of second UCIsaccording to the start position of the transmission resource of thefirst UCI and the start positions of the transmission resources of thesecond UCIs.

In an embodiment of the application, when the base station determinesthat the start position of the transmission resource of the first UCI isnot later than the start position of transmission resource of any secondUCI or a first second UCI or a second UCI with the earliest startposition among the transmission resources of the plurality of secondUCIs, then the base station determines the transmission resource of thefirst second UCI or the second UCI with the earliest start positionamong the transmission resources of the plurality of second UCIs as theselected transmission resource of the second UCI; when the base stationdetermines that the start position of the transmission resource of thefirst UCI is later than the start position of transmission resource of afirst second UCI or a second UCI with the earliest start position amongthe transmission resources of the plurality of second UCIs, then thebase station determines the transmission resource of a second or lastsecond UCI or a second UCI with the second earliest start position amongthe transmission resources of the plurality of second UCIs as theselected transmission resources of the second UCI.

Further, the first UCI and the plurality of second UCIs are any one of:Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK), periodicChannel State Information (CSI) and Scheduling Request (SR). For theplurality of second UCIs, the plurality of second UCIs may includesecond UCIs of a same message type; or the plurality of second UCIs mayinclude second UCIs of at least two different message types.

Furthermore, the combinations of the first UCI and the plurality ofsecond UCIs include but not limited to the following examples.

It should be noted that, before performing the step 502, the basestation may further determine whether simultaneous transmission of thefirst UCI and the second UCIs is supported; and the base station selectsa transmission resource of a second UCI among the transmission resourcesof the plurality of second UCIs according to the start position of thetransmission resource of the first UCI and the start positions of thetransmission resources of the second UCIs when the simultaneoustransmission of the first UCI and the second UCIs is supported.

Step 503: the base station receives the first UCI and the second UCIcarried by the selected transmission resource of the second UCIsimultaneously on the selected transmission resource of the second UCI.

Since the UCI combined transmission process performed by the basestation side corresponds to that performed by the user equipment side,it will not be repeated here.

Therefore, on the network side, for example, on the base station side,the above method can ensure that the base station and the user equipmenthave the same understanding of UCI combined transmission when thetransmission resources of different UCIs overlap in the time domain; andthe above method can also avoid the redundant transmission of the firstUCI while ensuring that the base station can obtain the UCI timely.

The combined transmission method of the uplink control information willbe described in detail below in combination with some embodiments.

First Embodiment

As shown in FIG. 6, it is assumed that the first UCI is SR andtransmitted using the PUCCH format 0, the transmission resource of theSR is PUCCH-0, which occupies 2 symbols. There are 2 second UCIs, bothof which are SPS HARQ-ACKs (referred to as SPS ANs in FIG. 6) andtransmitted using the PUCCH format 0, wherein the transmission resourceof the first SPS HARQ-ACK is PUCCH-1 which occupies 1 symbol, and thetransmission resource of the second SPS HARQ-ACK is PUCCH-2 which alsooccupies 1 symbol.

It can be seen from FIG. 6 that the start position of the transmissionresource (PUCCH-0) of the SR is aligned with the start position of thetransmission resource (PUCCH-1) of the first SPS HARQ-ACK, that is, thestart position of the PUCCH-0 is no later than the start position of thePUCCH-1 and is earlier than the start position of the transmissionresource (PUCCH-2) of the second SPS HARQ-ACK, so the SR and the firstSPS HARQ-ACK can be transmitted on the PUCCH-1, and only the second SPSHARQ-ACK is transmitted on the PUCCH-2.

When the state of the SR is positive, the user equipment can transmitthe positive SR and the first SPS HARQ-ACK on the PUCCH-1. Specifically,the user equipment may transmit the first SPS HARQ-ACK on the PUCCH-1 byusing the cyclic shift corresponding to the positive SR state toimplicitly express that the PUCCH-1 also carries the positive SRinformation.

When the state of the SR is negative, the user equipment can transmitthe negative SR and the first SPS HARQ-ACK on the PUCCH-1. Specifically,the user equipment may transmit the first SPS HARQ-ACK on the PUCCH-1 byusing the cyclic shift corresponding to the negative SR state toimplicitly express that the PUCCH-1 also carries the negative SRinformation.

Correspondingly, when the network-side device encounters the situationdescribed in FIG. 6, the method adopted is similar, and the details arenot repeated here.

Second Embodiment

As shown in FIGS. 7a, 7b and 7c , it is assumed that the first UCI is SRand transmitted using the PUCCH format 1, the transmission resource ofthe SR is PUCCH-0, which occupies 8 symbols. There are 2 second UCIs,both of which are SPS HARQ-ACKs (referred to as SPS ANs in FIGS. 7a, 7band 7c ) and transmitted using the PUCCH format 0, wherein thetransmission resource of the first SPS HARQ-ACK is PUCCH-1 whichoccupies 2 symbols, and the transmission resource of the second SPSHARQ-ACK is PUCCH-2 which also occupies 2 symbols.

It can be seen from FIG. 7a that the start position of the transmissionresource (PUCCH-0) of the SR is aligned with the start position of thetransmission resource (PUCCH-1) of the first SPS HARQ-ACK, that is, thestart position of the PUCCH-0 is no later than the start position of thePUCCH-1 and is earlier than the start position of the transmissionresource (PUCCH-2) of the second SPS HARQ-ACK, so the SR and the firstSPS HARQ-ACK can be transmitted on the PUCCH-1, and only the second SPSHARQ-ACK is transmitted on the PUCCH-2.

When the state of the SR is positive, the user equipment can transmitthe positive SR and the first SPS HARQ-ACK on the PUCCH-1. Specifically,the user equipment may transmit the first SPS HARQ-ACK on the PUCCH-1 byusing the cyclic shift corresponding to the positive SR state toimplicitly express that the PUCCH-1 also carries the positive SRinformation.

When the state of the SR is negative, the user equipment can transmitthe negative SR and the first SPS HARQ-ACK on the PUCCH-1. Specifically,the user equipment may transmit the first SPS HARQ-ACK on the PUCCH-1 byusing the cyclic shift corresponding to the negative SR state toimplicitly express that the PUCCH-1 also carries the negative SRinformation.

It can be seen from FIG. 7b that the start position of the transmissionresource (PUCCH-0) of the SR is earlier than the start position of thetransmission resource (PUCCH-1) of the first SPS HARQ-ACK, and isearlier than the start position of the transmission resource (PUCCH-2)of the second SPS HARQ-ACK, so the SR and the first SPS HARQ-ACK can betransmitted on the PUCCH-1, and only the second SPS HARQ-ACK istransmitted on the PUCCH-2.

When the state of the SR is positive, the user equipment can transmitthe positive SR and the first SPS HARQ-ACK on the PUCCH-1. Specifically,the user equipment may transmit the first SPS HARQ-ACK on the PUCCH-1 byusing the cyclic shift corresponding to the positive SR state toimplicitly express that the PUCCH-1 also carries the positive SRinformation.

When the state of the SR is negative, the user equipment can transmitthe negative SR and the first SPS HARQ-ACK on the PUCCH-1. Specifically,the user equipment may transmit the first SPS HARQ-ACK on the PUCCH-1 byusing the cyclic shift corresponding to the negative SR state toimplicitly express that the PUCCH-1 also carries the negative SRinformation.

It can be seen from FIG. 7c that the start position of the transmissionresource (PUCCH-0) of the SR is later than the start position of thetransmission resource (PUCCH-1) of the first SPS HARQ-ACK, but isearlier than the start position of the transmission resource (PUCCH-2)of the second SPS HARQ-ACK, so the SR and the second SPS HARQ-ACK can betransmitted on the PUCCH-2, and only the first SPS HARQ-ACK istransmitted on the PUCCH-1.

When the state of the SR is positive, the user equipment can transmitthe positive SR and the second SPS HARQ-ACK on the PUCCH-2.Specifically, the user equipment may transmit the second SPS HARQ-ACK onthe PUCCH-2 by using the cyclic shift corresponding to the positive SRstate to implicitly express that the PUCCH-1 also carries the positiveSR information.

When the state of the SR is negative, the user equipment can transmitthe negative SR and the second SPS HARQ-ACK on the PUCCH-2.Specifically, the user equipment may transmit the second SPS HARQ-ACK onthe PUCCH-2 by using the cyclic shift corresponding to the negative SRstate to implicitly express that the PUCCH-1 also carries the negativeSR information.

Correspondingly, when the network-side device encounters the situationdescribed in any one of FIGS. 7a, 7b and 7c , the method adopted issimilar, and the details are not repeated here.

Third Embodiment

As shown in FIGS. 8a, 8b and 8c , it is assumed that the first UCI isSPS HARQ-ACK (referred to as SPS AN in FIGS. 8a, 8b and 8c ) andtransmitted using the PUCCH format 1, the transmission resource of theSPS HARQ-ACK is PUCCH-0, which occupies 10 symbols; there are 2 secondUCIs, both of which are SRs and transmitted using the PUCCH format 1,wherein the transmission resource of the first SR is PUCCH-1 whichoccupies 4 symbols, and the transmission resource of the second SR isPUCCH-2 which also occupies 4 symbols.

It can be seen from FIG. 8a that the start position of the transmissionresource (PUCCH-0) of the SPS HARQ-ACK is aligned with the startposition of the transmission resource (PUCCH-1) of the first SR, thatis, the start position of the PUCCH-0 is no later than the startposition of the PUCCH-1 and is earlier than the start position of thetransmission resource (PUCCH-2) of the second SR, so the SPS HARQ-ACKand the first SR can be transmitted on the PUCCH-1, and only the secondSR is transmitted on the PUCCH-2.

When the states of the two SRs are both positive, the user equipment cantransmit the SPS HARQ-ACK and the first positive SR on the PUCCH-1, thatis, it implicitly express that the PUCCH-1 also carries the positive SRinformation by transmitting the SPS HARQ-ACK on the PUCCH-1; and onlythe second positive SR is transmitted on the PUCCH-2.

When the state of only one of the two SRs is positive, the userequipment can transmit through many methods. First method: the userequipment can transmit the SPS HARQ-ACK on the PUCCH resourcecorresponding to the positive SR to implicitly express that the resourcealso carries the positive SR information; and cannot transmit on thePUCCH resource corresponding to the negative SR. Second method: the userequipment can perform a timeline judgment on the overlapping combinationof the PUCCH resource corresponding to the positive SR and the PUCCHresource of the SPS HARQ-ACK; when the earliest channel in theoverlapping combination meets the timeline, the SPS HARQ-ACK and thepositive SR are transmitted on the PUCCH resource corresponding to thepositive SR, where the specific transmission process is the same as thefirst method; when the earliest channel in the overlapping combinationdoes not meet the timeline, it is considered to be wrong scheduling, andthe UE can autonomously choose how to transmit, and the specificbehavior is not specified.

When the states of the two SRs are both negative, the user equipment cantransmit the HARQ-ACK on the PUCCH resource (PUCCH-0) corresponding tothe SPS HARQ-ACK to implicitly express the negative SR information.

It can be seen from FIG. 8b that the start position of the transmissionresource (PUCCH-0) of the SPS HARQ-ACK is earlier than the startposition of the transmission resource (PUCCH-1) of the first SR, and isearlier than the start position of the transmission resource (PUCCH-2)of the second SR, so the SPS HARQ-ACK and the first SR can betransmitted on the PUCCH-1, and only the second SR is transmitted on thePUCCH-2.

When the states of the two SRs are both positive, the user equipment cantransmit the SPS HARQ-ACK and the first positive SR on the PUCCH-1, thatis, implicitly express that the PUCCH-1 also carries the positive SRinformation by transmitting the SPS HARQ-ACK on the PUCCH-1; and onlythe second positive SR is transmitted on the PUCCH-2.

When the state of only one of the two SRs is positive, the userequipment can transmit through many methods. First method: the userequipment can transmit the SPS HARQ-ACK on the PUCCH resourcecorresponding to the positive SR to implicitly express that the resourcealso carries the positive SR information; and cannot transmit on thePUCCH resource corresponding to the negative SR. Second method: the userequipment can perform a timeline judgment on the overlapping combinationof the PUCCH resource corresponding to the positive SR and the PUCCHresource of the SPS HARQ-ACK; when the earliest channel in theoverlapping combination meets the timeline, the SPS HARQ-ACK and thepositive SR are transmitted on the PUCCH resource corresponding to thepositive SR, where the specific transmission process is the same as thefirst method; when the earliest channel in the overlapping combinationdoes not meet the timeline, it is considered to be wrong scheduling, andthe UE can autonomously choose how to transmit, and the specificbehavior is not specified.

When the states of the two SRs are both negative, the user equipment cantransmit the HARQ-ACK on the PUCCH resource (PUCCH-0) corresponding tothe SPS HARQ-ACK to implicitly express the negative SR information.

It can be seen from FIG. 8c that the start position of the transmissionresource (PUCCH-0) of the SPS HARQ-ACK is later than the start positionof the transmission resource (PUCCH-1) of the first SR, but is earlierthan the start position of the transmission resource (PUCCH-2) of thesecond SR, so the user equipment can transmit the SPS HARQ-ACK and thesecond SR on the PUCCH-2, and transmit only the first SR on the PUCCH-1.

When the states of the two SRs are both positive, the user equipment cantransmit the SPS HARQ-ACK and the second positive SR on the PUCCH-2,that is, implicitly express that the PUCCH-2 also carries the positiveSR information by transmitting the SPS HARQ-ACK on the PUCCH-2; and onlythe first positive SR is transmitted on the PUCCH-1.

When the state of only one of the two SRs is positive, the userequipment can transmit through many methods. First method: the userequipment can transmit the SPS HARQ-ACK on the PUCCH resourcecorresponding to the positive SR to implicitly express that the resourcealso carries the positive SR information; and cannot transmit on thePUCCH resource corresponding to the negative SR. Second method: the userequipment can perform a timeline judgment on the overlapping combinationof the PUCCH resource corresponding to the positive SR and the PUCCHresource of the SPS HARQ-ACK; when the earliest channel in theoverlapping combination meets the timeline, the SPS HARQ-ACK and thepositive SR are transmitted on the PUCCH resource corresponding to thepositive SR, where the specific transmission process is the same as thefirst method; when the earliest channel in the overlapping combinationdoes not meet the timeline, it is considered to be wrong scheduling, andthe UE can autonomously choose how to transmit, and the specificbehavior is not specified.

When the states of the two SRs are both negative, the user equipment cantransmit the HARQ-ACK on the PUCCH resource (PUCCH-0) corresponding tothe SPS HARQ-ACK to implicitly express the negative SR information.

Correspondingly, when the network-side device encounters the situationdescribed in any one of FIGS. 8a, 8b and 8c , the method adopted issimilar, and the details are not repeated here.

Fourth Embodiment

As shown in FIGS. 9a, 9b and 9c , it is assumed that the first UCI is SRand transmitted using the PUCCH format 1, the transmission resource ofthe SR is PUCCH-0, which occupies 8 symbols; there are 2 second UCIs,both of which are CSIs and transmitted using the PUCCH format 2, whereinthe transmission resource of the first CSI is PUCCH-1 which occupies 2symbols, and the transmission resource of the second CSI is PUCCH-2which also occupies 2 symbols.

It can be seen from FIG. 9a that the start position of the transmissionresource (PUCCH-0) of the SR is aligned with the start position of thetransmission resource (PUCCH-1) of the first CSI, that is, the startposition of the PUCCH-0 is no later than the start position of thePUCCH-1 and is earlier than the start position of the transmissionresource (PUCCH-2) of the second CSI, so the SR and the first CSI can betransmitted on the PUCCH-1, and only the second CSI is transmitted onthe PUCCH-2.

Further, the user equipment may transmit the X-bit SR and the first CSIsimultaneously on the PUCCH resource (PUCCH-1) corresponding to thefirst CSI, wherein X is ┌log₂(K+1)┐ and K is the number of overlapped SRconfigurations in the time domain, that is, regardless of whether thestate of the SR is positive or negative, the user equipment needs totransmit the X-bit SR; and furthermore, when there is only one SRconfiguration, X=1.

It can be seen from FIG. 9b that the start position of the transmissionresource (PUCCH-0) of the SR is earlier than the start position of thetransmission resource (PUCCH-1) of the first CSI, and is earlier thanthe start position of the transmission resource (PUCCH-2) of the secondCSI, so the user equipment can transmit the SR and the first CSI on thePUCCH-1, and transmit only the second CSI on the PUCCH-2. The specifictransmission method can refer to the content described above, and willnot be repeated here.

It can be seen from FIG. 9c that the start position of the transmissionresource (PUCCH-0) of the SR is later than the start position of thetransmission resource (PUCCH-1) of the first CSI, but is earlier thanthe start position of the transmission resource (PUCCH-2) of the secondCSI, so the user equipment can transmit the SR and the second CSI on thePUCCH-2, and transmit only the first CSI on the PUCCH-1.

Further, the user equipment may transmit the X-bit SR and the second CSIsimultaneously on the PUCCH resource (PUCCH-2) corresponding to thesecond CSI, wherein X is ┌log₂(K+1)┐ and K is the number of overlappedSR configurations in the time domain, that is, regardless of whether thestate of the SR is positive or negative, the user equipment needs totransmit the X-bit SR; and furthermore, when there is only one SRconfiguration, X=1.

Correspondingly, when the network-side device encounters the situationdescribed in any one of FIGS. 9a, 9b and 9c , the method adopted issimilar, and the details are not repeated here.

An embodiment of the application further provides a user equipment,which can perform the foregoing method embodiments. The user equipmentaccording to the embodiment of the application is as shown in FIG. 10,and the user equipment 1000 includes: a determining device 1001, aselection device 1002, and a transmission device 1003, wherein:
